A MOSFET or IGBT that is grounded-referenced and not floating is referred to as a high-side switch.
A high-side MOSFET is one whose source terminal is attached to the circuit ground and is used in boost converters.
The Global high-Side MOSFET Driver market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A non-isolated gate driver family that can be utilised as a high-side driver because of its fully differential control inputs is part of the EiceDRIVER family of isolated gate drivers from Infineon Technologies, level-shift gate driver alternatives, and gate driver ICs.
They offer one-channel and two-channel galvanically isolated-gate driver integrated circuits (ICs). Others of these ICs have sophisticated protection features like active Miller clamp and DESAT, and some are UL and VDE certified.
To best suit the driving of OptiMOS power MOSFETs, CoolMOS superjunction MOSFETs, CoolSiC MOSFETs, and CoolGaN HEMTs, a variety of UVLO threshold settings are provided.
When high-side voltages do not exceed 100V, as in some buck-boost circuits, battery-powered motor drive applications, and half-bridge or full-bridge synchronous rectification units, the non-isolated TDI gate-driver family can be a desirable option.
A single-channel gate-driver integrated circuit (IC) called the 1EDN71x6U is designed to drive Infineon CoolGaN Schottky Gate HEMTs as well as other GaN SG HEMTs and Si MOSFETs.
A high-performance system design using GaN SG HEMTs is made possible by this gate driver’s Truly Differential Input, four driving strength options, active Miller clamp, and bootstrap voltage clamp.
A high-speed, high-side N-channel MOSFET driver called the LTC7004 is now available from Analog Devices, Inc., which recently bought Linear Technology Corporation. It can run at up to 60V of supply voltage. An external N-channel MOSFET switch can operate continuously thanks to the internal charge pump’s full enhancement.
The LTC7004’s potent 1 gate driver, which is well suited for both high frequency switching and static switch applications, can easily drive large gate capacitance MOSFETs with very low transition times and 35ns propagation delays.
The LTC7004 is made to swiftly drive a high side N-channel power MOSFET whose drain can be between 0V and 60V using a ground-referenced, low voltage digital input signal (65V abs max). The LTC7004 has a configurable undervoltage lockout and runs from a driver bias supply range of 3.5V to 15V.
Switching losses are kept to a minimum when driving a 1,000pF load because of the quick 13ns rise and fall periods. Other features include a programmable overvoltage lockout and a programmable turn-on slew rate.
The MSOP-10 packaging for the LTC7004 has pins set up for high voltage spacing. -40°C to 125°C for extended and industrial versions, -40°C to 150°C for high temperature automotive versions, and -55°C to 150°C for military grade versions are the three operational junction temperature ranges that are offered. Price per unit starts at $2.05 for 1,000 pieces.
The COVID-19 epidemic has had a severe influence on the global MOSFET drivers industry. An enormous drop in demand for these systems has resulted from the global stagnation of new projects. Due to workers staying at home, it has been difficult for global companies to integrate new MOSFET drivers, which has disrupted supply chains around the world.
Only the production and supply chain are stalled, therefore COVID-19’s effects on this market are only transitory. Production, supply chains, and demand for these embedded technologies will all progressively rise once the situation improves.
The usage of MOSFET drivers in consumer electronics, energy & power, and other applications has increased due to the need for compact automation solutions, higher performance, and durability. Due to their small size and improved durability, MOSFET drivers are therefore anticipated to experience moderate growth in the near future.
However, high implementation costs and present leakage are impeding market expansion. The market for MOSFET drivers is anticipated to have robust company expansion potential as a result of the integration of MOSFET drivers with the human machine interface (HMI).
